To all whom 'it may concern: A

Be it known that I, CHARLES H. OVER- KAMP, a citizen of the United States, residing at Cincinnati, Ohio, have invented a new and useful Im )rovement in Loaf-Forming Machines, of w ich the following is a speci; lcation.

My invention relates to loaf forming inachinos of the class adapted to the use of' bakers or others for forming loaves of bread,

buns, etc. and the objects of my improvements are to protide means for shaping predetermined quantitiesv of dough or other plastic material into substantially s herical 15 `forms; to' provide means for kiiea ing the material during its shaping process; to provide interchangeable means for driving the endless apron either continuously or intermittently as desired; to provide means for moving the forming board and the apron intermittently in unison; to provide means for simultaneously or for independently adjusting the extent of the movement of both the forming boa-rd and of the apron; to provide adjustable bearings ,for the apron guide roller, and Vto provide simple and durable construction and such assemblage of parts as will secure the greatest facility of operation and ellicicncy of action. These objects 39 are attained iii the following'described maiiner as illustrated in the accompanying drawings, in which Figure 1, is a front elevation with parts broken away of aloaf foruiin machine einbodying my improvements; ig. 2, an end elevation with parts removed; Fim. .3, a transverse section on the line a-a o Fig. `1, and Fig. et an elevationwith parts in section of the pawl and ratchet mechanism. f

In the drawings, `1 represents the liori zontal table su ported on legs 2 and formed with a longitn mal offset 3 in the rear portion of its surface. An endless apron 10 preferably'of canvas is carried on vertical drivf `ing and guide rollers 4 and 5 with its lower front edge in contact with the offset 3. The driving roller 4 is journaled at its respective ends inv one end'of the table and in a bracket 6 which is, secured on the table, and the guide roller 5 is journaled in bearings 7 and which .are .independently adjustable by means of hand screws 9 inthe op osite end of the table and, in stations brac et 11.

A stationary guide'boa 12 secured on 66 the tableserves to naintain the front portion `of the apron iii thesaine vertical plane and to prevent it .from yielding rearwardly under the pressure. of the dough on its survface. Shaft 13 journaled in bracket I+ and in one of the 'supporting legs Yis provided 60 with a driven pulley 15, and an eccentric 16. A spur gear 17 splined on said shaft` 1s uiov- -able longitudinally thereoiiby Vineaiis of a yoke lever 1S in the nsiuil manner. The inain shattli) jouiiialed inthe supporting legs 2 is provided with a. spur geur 21 which engages with gear li'A aud-transniits motion to the 'roller l by means of iiiitei.l wears 22.

,A rock shaft journaled in tlie end supporting legs and parallel with the niain shaft is provided with crank arms 2l and with Ya l rocker arin which is extended therefrom in'opposite directions and is formed with slots 26 and 27 in its respective end portions. l Anjeccentric rod 2Siictuatcd by the eccen- 75 tric ltis adj ustably secured at one end in slot 26 for imparting a rocking `motion to shaft 23. f lrackets 31. slidingly mounted in guides 32 which'are secured on ,the under side of the table are reciprocated in unison from the crank ariiis` 24 by nicafns of connecting rods A forming board 3l pret'- crably .fared 'with cavas or knurled and provided with a knife l?) in movable contact with the surface of the table is adjustably 35 secured to the brackctwiit differentinclined `angles to the table. in ront ofvaud with its staiitiall)v lieriwinliculai' to n planewhichbi- Q6 sects the angle between the face of theyiipron and the forming board 3l. A fixed vstop 3i) limits the downward swing of board Iit by.\ contacting with one of the links. A'staf,

`tional-vW apron il attached lo the d'isi-liarge 100 end o the table sei-ves to receive the loaws after they are formed.

Armel; 42' adjusta'bly secured in slot. 2T of the rocker :iini engages with a llauged i pinion 43 which is idly mounted on theinain 106 shaft i9. Said pinion carries a pawl 44 adapted toeiigage with u ratchet wheel 45 v'which is secured on said shaft and whereby said shaft may-be rotated iiiteiiiiittently for driving the apron in unison with the rearwa rd Amovements of the forming board. A ilour sifter (not shown) may be supported Wheel, or ihe d io shown by.

-the apron above the table and automaticall by ineansconnected with any; of t e moving members of the machine. In op eration, when it is desired to run the apron continuously, the pawl should be'` secured out of engagement with the` ratchet rack and pinion disconnected and the gear 17 engaged with the gear 21. For driving the apron intermittently, the rackl and pinion vvmechanism should be used and gear 17 disengaged from gear 21 as dotted-lines in Fig. 1. Predetermiiied quantities` y placed on the front end ofthe table'arere-l peatedly pressed againstl the apron by the movement of` theA forming board and si- Y l multaneously rolled in a rearward direction by the a ron and under the weight' of the gravity then discharged 0n the receiving apron.

The apron the apron un erproper tension. `The. moveforming board may be changed b the adjustment of theecceiitric rod in set 26, and; the intermittent fmovement of may be changed 5y the adjustment of the rack inslot 27 asdesired..

Havinfully vdescribed m'y improvement, what I c aim as my invention y,and desire to secure by Letters vPatent of the United States -is l v 1. A loaf forming machine comprising an endless apron, means for moving it intermital forming board longitudinally parallel with and laterally'iiiclined 'in relation to the apron, and means for reciprocating the board in a direction perpendicular. to the v apron and in unison with its'movements. l

Q. In a loaf `forming machine, `the com-1 'binatioii of la driven shaft,an endless apron, interchangeable means actuatedby the shaft for driving the apron either continuously or intermittently a forming board parallel with lche apron, and means for reciprocating it in aidirection perpendicular thereto.l l
